I confirm what Gene just posted.

Not sure if that answerd your question, but the whole command line is copied to /proc/cmdline thus available to the initrd.

For instance you could suggest the user to append to the boot command line (set by the selected boot entry of the bootloader config file) something like
 hostname=myhost
T
Then hostname will be set to "myhost" system wide as soon as the initrd is loaded. You don't even have to parse the command line yourself, this is done automatically.

This is commonly used for instance to set the parameters needed by the brltty daemon to adapt it to the screen reader in use.

Have a good day/Bonne journée
